Question

我尝试部署容器，但是不幸的是，当我尝试执行 kubectl apply -f * .yaml

时，我遇到了错误

错误是：

错误验证数据：ValidationError（Pod.spec.containers [1]）： io.k8s.api.core.v1.Container中的未知字段“ persistentVolumeClaim”；

我不明白为什么会收到错误消息，因为我在pd.yaml配置中的 persistentVolumeClaim：下写了 claimName：：（

Pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: karafpod
spec:
  containers:
  - name: karaf
    image: xxx/karaf:ids-1.1.0
    volumeMounts:
    - name: karaf-conf-storage
      mountPath: /apps/karaf/etc
  - name: karaf-conf-storage
    persistentVolumeClaim:
      claimName: karaf-conf-claim

PersistentVolumeClaimKaraf.yml

         volumeMounts:

           name: karaf-conf
       volumes:
       - name: karaf-conf
         persistentVolumeClaim:
           claimName: karaf-conf

Answer 1

根据kubernetes documentation，persistentVolumeClaim是.spec.volume级的一部分，而不是.spec.container对象的pod级的一部分。

正确的pod.yaml是：

apiVersion: v1
kind: Pod
metadata:
  name: karafpod
spec:
  volumes:
    - name: efgkaraf-conf-storage
      persistentVolumeClaim:
        claimName: efgkaraf-conf-claim
  containers:
    - name: karaf
      image: docker-all.attanea.net/library/efgkaraf:ids-1.1.0
      volumeMounts:
      - name: efgkaraf-conf-storage
        mountPath: /apps/karaf/etc

Answer 2

看到该错误的原因是由于您在Pod规范的容器规范下指定了persistentVolumeClaim。如您从自动生成的文档中看到的：https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.10/#container-v1-core

此级别/ API对象不支持

persistentVolumeClaims，这就是您所看到的错误的原因。

您应该修改pod.yml以将其指定为卷。

例如：

apiVersion: v1
kind: Pod
metadata:
  name: karafpod
spec:
  containers:
    - name: karaf
      image: xxx/karaf:ids-1.1.0
      volumeMounts:
      - name: karaf-conf-storage
        mountPath: /apps/karaf/etc
  volumes:
    - name: karaf-conf-storage
      persistentVolumeClaim:
        claimName: karaf-conf-claim

在Kubernetes中未知PersistentVolumeClaim
